Real Estate ROI & Cap Rate Calculator Description

Overview of ROI and Cap Rate

Real estate investors rely on two fundamental metrics—Return on Investment (ROI) and Capitalization Rate (Cap Rate)—to assess property performance. While both focus on profitability, they serve distinct purposes and calculations.

What is ROI?

ROI measures how much return an investor makes relative to the total amount invested. It includes all upfront and recurring costs, making it a comprehensive profitability metric.

ROI (%) = (Net Profit / Total Investment) * 100

• Net Profit: Income after all operating expenses and investment costs.
• Total Investment: Includes purchase price, renovations, closing fees, and other capital expenditures.

What is Cap Rate?

Cap Rate evaluates the property’s yield assuming a cash purchase. It’s ideal for comparing properties or markets without financing distortions.

Cap Rate (%) = (Net Operating Income / Property Value) * 100

• Net Operating Income (NOI): Annual income minus operating expenses (but excluding mortgage payments).
• Property Value: Market value or purchase price of the property.

Key Differences

• Cap Rate does not include financing costs or improvement expenses.
• ROI gives a broader picture of overall investment efficiency.

Important Edge Cases

• Negative NOI: Indicates operating losses. Both ROI and Cap Rate will reflect negative performance.
• Zero Rental Income: Results in undefined or negative ROI/Cap Rate, highlighting unproductive assets.
• Short-Term Rentals: Require detailed monthly tracking and annualization to avoid distorted ROI/Cap Rate values.
• Renovation-Heavy Properties: Large up-front costs can depress ROI despite strong Cap Rate projections.
• Financed Deals: ROI should account for loan interest, closing costs, and amortization, unlike Cap Rate.

Mini Case Study 1: Residential Duplex

Scenario: Jane buys a duplex for $250,000 and invests $20,000 in renovations. Annual rental income is $36,000, with $8,000 in expenses.

NOI = $36,000 - $8,000 = $28,000
ROI = ($28,000 / $270,000) * 100 = 10.37%
Cap Rate = ($28,000 / $250,000) * 100 = 11.2%

Analysis: This shows a healthy cash flow and favorable Cap Rate, indicating strong investment potential.

Mini Case Study 2: Small Office Property

Scenario: Alex purchases a commercial property for $1M, earning $120,000/year with $40,000 in expenses. The deal is financed with an 80% loan.

NOI = $120,000 - $40,000 = $80,000
Cap Rate = ($80,000 / $1,000,000) * 100 = 8.0%

Analysis: Despite a solid Cap Rate, true ROI is lower after accounting for loan interest and cash invested. This highlights the importance of distinguishing between the two metrics.
